SEA'LNG DEVCE EUR JAR-CAPS.

Specification of Letters Patent.

Patented Mar. i6, MM5.

Application filed June 16, i914. Serial No. $45,479.

T0 all whom it may concern Be it known that l, Harrelson S. limita,

itizen of the United tates, residing at Deodate, in the county of Bauphin and State of ennsylvania, have invented certain new and useful lmprovenients in Sealing Devices for dar-Caps, of which the following is a specification.

rlhis invention relates to an improved device for sealing closures and is especially designed for use in connection with circular metallic caps which are adapted to have screw threaded engagement with suitable ject to provide an implement of this character which may readily be operatively connected with the cap and rotated thereon to press the terminal radial flange formed at the outer extremity of the side wall of the cap into engagement with the gasket con nionly interposed between said flange and the body portion of the jar, to thus provide an air-tight closure.

The invention has as a. still further object to provide a device of this character which will be simple in construction and which may be used upon any conventional type of circular metallic jar cap as now on the market.

lilith these and other objects in view, my invention will be more fully described illustrated in the accompanying drawings, and then specifically pointed out in the claims which are attached to and form a part of this application.

in the accompanying drawings :FFigure l is a perspective View showing the manner in which my improved sealing device is apliec for use, the portion of the jar shown being conventionally illustrated. Fig. 2 is a transverse sectional view showing the device applied and particularly illustrating the manner in which the disk carried thereby is disposed. to engage the terminal flange of he cap, and Fig. 3 is a detail perspective view of the device.

Corresponding and like parts are referred in the following description and indicated all the views of the drawings by the same ference characters. For the purposes of convenience, illustrated in the drawings, the manner in which the improved device is applied and have conventionally shown a jar 1C- which is provided with the circular neck ll adapted to have screw threaded engagement with jars, the invention having as its primary oby l have the cap 12, the side wall of the cap being indicated at i8, which wall as usual, is formed with the terminal radially extending flange ill, said flange being arranged to engage against the gasket 15 which encircles the neck of the As is well known, the ordinary cap of this character is made of soft metal and is thus liable to accidental injur 1, and that any mutilation of the flange 14; such as would interrupt the dat bearing surface of said `flange arranged to contact with the gasket l5 will render the cap of no further use since the imperfect joint which would then be formed by the flange between the gasket l5 and the cap would permit air to gain access to the interior of the jar to effect the fermentation or spoiling of the contents thereof. T he present invention, therefore, seeks to provide a device by which the flange ist of the jar cap may be brought into close and interrupted engagement with the gasket l5 carried by the j ar, and so constructed that by rotating the device upon the cap, any inequalities in the bearing surface of said flange such as might have been brought about through the injury thereof may be rolled out so that the flange may form a perfect joint between the gasket and the cap.

Coming now to more particularly describe the invention, the body portion 16 thereof includes a substantially semi-circular preferably concave convex bearing flange 17 which presents the inner concave face i8. Formed on the upper edge of the bearing flange 17 and connecting the extremities thereof, is a transversely extending arm 19 and intersecting the arm 19 midway the ends thereof and extending at substantially right angles to said arm is an arm 20, the arm 2O being oined at its inner extremity, with the upper edge of the bearing flange 17 substantially midway the ends of said flange.

The arm 20, adjacent to its outer extremity is obliquely directed longitudinally as shown at 2l to extend away from the bearing flange 17 upon the contiguous side of said arm and the adjacent terminal 22 thereof is thence again directed longitudinally in reverse relation to extend obliquely toward the free lower edge of said flange. Mounted for rotation upon a suitable pin 23 and arranged adjacent the inner face of the inwardly directed terminal 22 of the arm 20 is a disk 24, the periphery of which is beveled to provide an inclined face 25 sloping away from the adjacent terminal of the arm 20.

In Figs. 1 and 2 of the drawings, I have shown the manner in which the device is applied in use and it will be observed that the side wall of the cap 12 is embraced by the bearingliange 17 land by the arm 20, the bearing flange being of a widthfslightly greater' than the side wall of the cap and bearing at its Vfree outer edge -upon the flange 14 thereof, while the obliquely directed portion 21 of the arm 2O is disposed to extend over the upper edge of the cap opposite the bearing flange 17 with the disk 24 bearing by its beveled face 25 upon the adjacent portion of the peripheral edge of said flange. It will be observed that owing to the angulardisposition of theterminal 23 of the arm 20, that when downward pres-V sure is exerted upon the body portionl 16, the disk- 24- will be caused to bearV downwardly and inwardly upon the peripheral edge of the flange 14 to not only thereby force the side wall of the cap into secure engagement withthe neck of the jar 10, but the flange 14 at its outer edge will also be brought into firm engagement with the gasket 15.

In practical use, it is intended that after the cap 12 of the jar has been applied thereto in the usual manner, that the device shall Y be placed upon'the cap as shown in Figs. 1

and 2 of the drawings, and kthen rotatedv thereon, ldownward pressure being exerted upon the body portion 16 as the deviceis rotated. It will beclear that the disk 24-may be lpassed over the flange 14 throughout its entire circumference as many times as desired and the inclined face 25 of said disk upon engaging the peripheral edgeY of the flange'will smooth out or roll out any inequalities therein which may have been brought about through accidental injury to the flange, to provvide a "smooth, uninterrupted bearing surface upon the inner face thereof to contact with the gasket 15, and

- will also bend the peripheral margin of said flange downwardly'and inwardly toward the neck of the jar to securely engage the gasket arranged thereon. tothe fact that while the disk 24 is arranged to contact with the yflange 14 at a substan tially obtuse angle thereto, the bearing flange 17 is arrangedto contact with kthe flange at substantially right angles thereto, the disk having a tendency tokk force said flangey downwardly and inwardly as above stated, toward the neck of the j ar, while the bearing flange 17 is disposed Vto force said flange downwardly toward the body portion of the jar when pressure is applied thereto, to bring said flange throughout its enti-re width, into contact with the gasket 15. Thus, when the device is rotated about the cap 12,l the flange 14 of said cap will, not only be forced Vdownwardly to bear flatly against the gasket Attention is also* calledv said gasket; The'efective sealing ofthe jar is thus secured and it will benoted that the device-is exceedingly simple in construction and may be readily applied and used. Attention is also called to the fact that'wh'en downward pressure is exertedl upon the body portion 16 in the practical use of the device, that the free edge of the bearing flange 17 which restsupon the flange 14 of thecap 12 will be caused to coactwith the disk 24 to smooth out any `inequalities in the surface of the flange 14, such as slight depressions or l Vupwardly projecting portions in said flange to thus insure the provision ofjan uninterrupted flat bearing surface' upon the inner face of said flange, such surface being dis posed to contact with the gasket 14 or 'with the body portion ofthe jar proper as the case may be. However, it will be clear that equal effectiveness upon jar caps which have `not previously been applied in use, and have ymy improved device may be employed with a very eiiicient construction for the purpose Y set forth and that the complete'device may be readily manufactured in accommodate the diameters or the various heights of different jar caps.

I claim and desire to secure by ent is y 1. A device of the character describedV including a body portion adapted toengage a jar cap to be rotated thereon, said body portion being integrally formed and including a substantially semi-circular bearing flange, anarm extending from one edge of said flange to project laterally upon one side of the concave face thereof, said arm being obliquely directedk longitudinally adjacent its outer extremity and the terminal thereof? thence obliquely directed longitudinallyin reverse relation to said Vfirst mentioned ob# liquely directed portion to extendV inwardly toward the said flange, anda disk mounted for rotation upon thesaid terminal of the arm, said disk beingbeveled upon its pe-Y riphery inwardly toward said langeand arranged to contact with the peripheral'mar-V gin of theterminal flange of the jar cap.
